[0002] After edge banding, panel furniture typically requires trimming and scraping, which are usually done by the trimming and scraping devices on the edge banding machine. While existing technologies exist that integrate trimming and scraping mechanisms, they suffer from the following drawbacks: they are independent, lack integration, occupy a large space, and cannot be used with an automatic tool-changing spindle. Summary of the Invention

When the sliding component is subjected to an external force from the target object to be trimmed, it can keep the fixed component stationary while sliding relative to the fixed component. When the sliding component slides relative to the fixed component, the fixed component is subjected to the action of the sliding component and generates a reaction force to drive the sliding component to stop or slow down its continued movement along the current direction, so as to control the range of movement of the sliding component caused by the external force, so that the range of movement is within a controllable range.

[0005] Furthermore, the fixing assembly includes an upper base, and a drive input tool holder, a left elastic element, a right elastic element, and a slider connecting seat mounted on the upper base. The sliding assembly includes an upper trimming part, a lower trimming part, a lower base, and a transverse guide rail, a driven gear, a limit block, a stop plate, and a stop block mounted on the lower base. The limit block is connected to the slider connecting seat.

[0006] Furthermore, the limiting block is provided with a protrusion, which is fixedly connected to the lower base.

[0007] Furthermore, the sliding assembly also includes a cylinder, an upper scraper, and a lower scraper. The upper and lower scrapers are used to scrape the edge of the sealing strip. The upper and lower scrapers are positioned on the same side of the sliding assembly and are spaced apart vertically. A blocking block is located on one side of the upper and lower scrapers and is directly opposite the spaced area between the upper and lower scrapers. The output shaft of the cylinder is connected to the upper scraper, and the cylinder is used to drive the upper scraper to move.

The lower scraping component is provided with a second height adjustment component, which can slide relative to the upper scraping component to adjust the height of the scraping component extending from the lower scraping component.

[0009] Furthermore, the sliding assembly also includes a rotating shaft connected to a drive input tool holder. The upper trimming piece and the lower trimming piece are mounted on the rotating shaft and can slide up and down. The upper trimming piece and the lower trimming piece are mounted on the side of the sliding assembly opposite to the upper and lower scraping pieces, and the upper trimming piece and the lower trimming piece are spaced apart. The drive input tool holder is used to drive the trimming blades on the upper trimming piece and the lower trimming piece to rotate by rotating the drive rotating shaft.

[0010] Furthermore, the upper trimming component includes an upper bearing, an upper trimming connector, an upper trimming cutter, and an upper slide block. The upper trimming cutter is mounted on an upper spline sleeve, which is fitted onto a rotating shaft. The upper bearing is mounted on the upper spline sleeve and the upper trimming connector.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-12 As shown, a flexible edge trimming integrated mechanism includes a fixed component 100 and a sliding component 200. The sliding component 200 can slide relative to the fixed component 100 under the action of an external force from the target object to be trimmed. When the sliding component 200 slides relative to the fixed component 100, the fixed component 100 generates a reaction force under the action of the sliding component 200, so as to drive the sliding component 200 to stop or slow down its continued movement along the current direction, thereby controlling the range of movement of the sliding component 200 under the action of the external force, so that the range of movement is within a controllable range.

[0017] Understandably, when trimming and / or scraping the edge banding on the target board, the sliding component 200 will slide relative to the fixed component 100 due to the force exerted by the target board. At this time, the fixed component 100 provides a reaction force, thereby preventing or slowing down the sliding component 200's sliding. This ensures that the sliding component 200 avoids excessive movement, maintaining a suitable degree of contact with the target board and ensuring that the force between the sliding component 200 and the edge banding on the target board is appropriate. This avoids excessive pressure (i.e., excessive force) on the edge banding, preventing damage, and also avoids insufficient force, which would prevent effective scraping or trimming. In other words, by achieving adjustable elasticity between the sliding component 200 and the edge banding, a buffering effect is achieved, preventing damage to the edge banding due to excessive force or ineffective trimming and scraping due to insufficient force.

[0018] For example, the fixing component 100 includes an upper base 29, and a drive input handle 1, a slider connecting seat 3, a left elastic element 26, and a right elastic element 4 mounted on the upper base 29. The sliding component 200 includes an upper trimming part 300, a lower trimming part 400, a lower base 24, and a transverse guide rail 5, a driven gear 28, a limiting block 32, a blocking plate 18, and a blocking block 31 mounted on the lower base 24. The drive input handle 1 is connected to the upper trimming part 300 and the lower trimming part 400 and is used to drive the upper trimming part 300 and the lower trimming part 400 to rotate. The upper trimming part 300 and the lower trimming part 400 are used to trim the edge banding tape. The slider connecting seat 3 is mounted on the transverse guide rail 5. The transverse guide rail 5 can slide relative to the slider connecting seat 3, that is, the slider connecting seat 3 can remain fixed, and the transverse guide rail 5 slides relative to the slider connecting seat 3, thereby allowing the sliding component 200 to slide relative to the fixing component 100 through the transverse guide rail 5.

[0019] The blocking plate 18 and the blocking block 31 are respectively installed on the left and right sides of the sliding assembly 200. The blocking plate 18 is used to abut against and bear the force from the plate during trimming, and the blocking block 31 is used to abut against and bear the force from the plate during scraping, so that the sliding assembly 200 moves to the right or left due to the force from the plates on both sides.

[0020] The limiting block 32 is provided with a protruding block 34. The limiting block 32 is fixedly connected to the lower base 24. The protruding block 34 on the limiting block 32 extends into the through hole (not shown in the figure) on the slider connecting seat 3, and the size of the through hole is larger than the size of the protruding block 34, so that when the limiting block 32 is moved by external force, the protruding block 34 can move left and right within the through hole. The left elastic element 26 and the right elastic element 4 each include a screw, a spring, a locking nut, and a limiting ring. The spring is sleeved on the screw, the locking nut is fixedly connected to one end of the screw, and the limiting ring is movably connected to the other end of the screw, so that the limiting ring can slide on the screw. The two ends of the spring are respectively connected to the locking nut and the limiting ring. The other end of the screw passes through the protruding block 34 and is threadedly connected to the slider connecting seat 3, so that the screw and the slider connecting seat 3 are fixedly connected. The left elastic element 26 is fixedly connected to the left side of the slider connecting seat 3, and the right elastic element 4 is fixedly connected to the right side of the slider connecting seat 3. The screw is movably connected to the protrusion 34 of the limiting block 32, the left elastic element 26 is movably connected to the protrusion 34 on the left side of the limiting block 32, and the right elastic element 4 is movably connected to the protrusion 34 on the right side of the limiting block 32.

[0021] refer to Figure 5 and Figure 6 The slider connecting seat 3 includes a horizontal plate with two first through holes. A vertical plate (not shown in the figure) is provided on each of the left and right sides of the horizontal plate. A second through hole is provided on the vertical plate. The second through hole on the left vertical plate is connected to the corresponding first through hole. The second through hole on the right vertical plate is connected to another second through hole. The left elastic element 26 is installed in the second through hole of the left vertical plate, and the right elastic element 4 is installed in the second through hole of the right vertical plate.

[0022] When in use, the sliding component 200 slides to the right due to the force exerted by the left side plate. Since the limiting block 32 is fixedly connected to the lower base 24 of the sliding component 200, the limiting block 32 also moves to the right. The limiting block 32 causes the left elastic element 26 and the right elastic element 4 to move to the right together. Simultaneously, since the slider connecting seat 3 remains stationary (the fixed assembly 100 containing the slider connecting seat 3 is typically fixedly suspended on the edge banding machine), the left elastic element 26 experiences a reaction force to the left from the slider connecting seat 3. This compresses the spring on the left elastic element 26, preventing it from moving further to the right. This, in turn, prevents the limiting block 32 from moving to the right, and consequently prevents the sliding assembly 200 from moving to the right as a whole. This effectively prevents or slows down the tendency to continue moving to the right, ensuring that the rightward movement caused by the force exerted by the material on the right is minimal (e.g., about 2 mm), within a controllable range. This ensures that even when the material and the sliding assembly 200 come into contact, excessive pressure on the material is avoided, thus ensuring that the force acting on the edge banding strip on the material is appropriate and preventing damage to the edge banding strip. Similarly, when subjected to a force from the right side of the material, the right elastic element 4 also ensures that the rightward movement caused by the force exerted by the material on the right is minimal. This ensures that whether the board is subjected to force on the left or right side, the edge banding will not be subjected to excessive force, thus protecting the edge banding from damage.

[0023] Since the compression of the spring on the elastic element (left elastic element 26, right elastic element 4) is limited and controllable after adjustment, the force is also controllable.

[0024] To avoid insufficient force from contact with the edge banding tape, simply adjust the tightness of the contact with the edge banding tape in the initial state.

[0025] For example, a horizontal guide rail 5 is provided on each of the left and right sides of the lower base 24, and the fixing component 100 is installed on the two horizontal guide rails 5 to maintain better stability.

[0026] For example, the fixing component 100 also includes a plurality of slider seats 6, which are mounted on the transverse guide rail 5. The transverse guide rail 5 can slide relative to the slider seats 6, that is, the slider seats 6 can remain fixed, and the transverse guide rail 5 can slide relative to the slider seats 6.

[0027] It is understandable that by setting the slider seat 6 to remain fixed and the transverse guide rail 5 to slide relative to the slider seat 6, the fixing component 100 can remain fixed and the sliding component 200 can slide relative to the fixing component 100. This allows the flexible edge trimming and scraping integrated mechanism to be used on equipment such as edge banding machines or edge banding processing centers, so that the fixing component 100 can be fixedly suspended on the edge banding machine for use on the board to be trimmed and scraped with edge banding tape.

[0028] For example, the sliding assembly 200 further includes a cylinder 30, an upper scraping member 10, and a lower scraping member 13. The upper scraping member 10 and the lower scraping member 13 are used to scrape the edge of the sealing tape. The upper scraping member 10 and the lower scraping member 13 are positioned on the same side of the sliding assembly 200 and are spaced apart vertically. A blocking block 31 is installed on the lower scraping member 13 and is located on one side of the upper scraping member 10 and the lower scraping member 13, directly opposite the spaced area between the upper scraping member 10 and the lower scraping member 13. This allows the board to be located in the area between the upper scraping member 10 and the lower scraping member 13, so that the upper scraping member 10 can contact the upper surface of the board, the lower scraping member 13 can contact the lower surface of the board, and the blocking block 31 abuts against the side of the board. The output shaft 8 of the cylinder 30 is connected to the upper scraping member 10. The cylinder 30 is used to drive the upper scraping member 10 to move, so that the upper scraping member 10 moves closer to or further away from the lower scraping member, thereby adjusting the distance between the upper scraping member 10 and the lower scraping member 13 to accommodate plates of different thicknesses.

[0029] It also includes a connecting plate 9, the output shaft 8 is connected to the connecting plate 9, and the connecting plate 9 is connected to the upper scraping piece 10, thereby realizing the connection between the output shaft 8 of the cylinder 30 and the upper scraping piece 10.

[0030] For example, the upper edge scraping member 10 is provided with a first height adjusting member 11, which can slide relative to the upper edge scraping member 10 to adjust the height extending beyond the upper edge scraping member 10. The lower edge scraping member 13 is provided with a second height adjusting member 14, which can slide relative to the upper edge scraping member 10 to adjust the height extending beyond the lower edge scraping member 13. The first height adjusting member 11 and the second height adjusting member 14 are arranged vertically at intervals. By adjusting the first height adjusting member 11 and the second height adjusting member 14, the gap width between the first height adjusting member 11 and the second height adjusting member 14 can be adjusted, thereby achieving fine-tuning of the gap and better adapting to boards of different thicknesses.

[0031] The height adjustment component allows for sliding relative to the scraping component, which is existing technology. Its main principle is to achieve sliding adjustment (i.e., height adjustment) by using the cooperation of springs and nut. This purpose can be achieved by changing the compression degree of the spring by tightening or loosening the nut. Since these are existing technologies, they will not be described in detail here.

[0032] For example, the sliding assembly 200 further includes a rotating shaft 23, which is connected to the drive input knife holder 1. The upper trimming piece 300 and the lower trimming piece 400 are mounted on the rotating shaft 23, on the side of the sliding assembly 200 opposite to the upper scraping piece 10 and the lower scraping piece 13. That is, the upper trimming piece 300 and the lower trimming piece 400 are also located on the same side and are spaced apart. The drive input knife holder 1 is used to drive the rotating shaft 23 to rotate, thereby rotating the trimming knives on the upper trimming piece 300 and the lower trimming piece 400, achieving trimming by rotating the trimming knives. Both the upper trimming piece 300 and the lower trimming piece 400 are used to trim the upper and lower sections of the edge banding on the board.

[0033] For example, the upper trimming component 300 includes an upper bearing 35, an upper trimming connector 20, an upper trimming cutter 19, an upper spline sleeve 21, and an upper slider seat 38. The upper trimming cutter 19 is mounted on the upper spline sleeve 21, which is sleeved on the rotating shaft 23 and can slide up and down. The upper bearing 35 is mounted on the upper spline sleeve 19 and the upper trimming connector 20, so that the rotating shaft 23 can drive the upper trimming cutter 19 to rotate relative to the upper trimming connector 20. The upper trimming connector 20 is mounted on the upper slider seat 38. The lower trimming component 400 includes a lower bearing 36, a lower trimming connector 15, a lower trimming cutter 17, a lower spline sleeve 37, and a lower slide block seat 39. The lower spline sleeve 37 is fitted onto the rotating shaft 23. The lower bearing 36 is mounted on the lower spline sleeve 37 and the lower trimming connector 20. The lower spline sleeve 37 is fitted onto the rotating shaft, so that the rotating shaft 23 can drive the upper trimming cutter 19 to rotate relative to the lower trimming connector 15. The lower trimming connector 15 is mounted on the lower slide block seat 39.

[0034] The sliding assembly 200 also includes a tension adjustment component 500. The lower trimming component 400 and the lower scraping component 13 are connected together by the lower trimming connector and the lower slide block 39. The tension adjustment component 500 is used to adjust the force exerted by the lower trimming blade 17 on the lower trimming component 400 and the lower scraping blade on the lower scraping component 13 on the sheet metal to adjust the processing amount.

[0035] It is understandable that the tension adjustment component 500 mainly includes a nut and a spring. By adjusting the tension of the spring through the nut, the tension adjustment component 500 can adjust the force exerted by the lower trimmer 17 and the lower scraper on the sheet metal, thereby adjusting the processing amount. Since the tension adjustment component 500 that realizes this function is existing technology, it will not be described in detail here.

[0036] For example, a fourth height adjustment component 22 is installed on the upper trimming component 300, and a third height adjustment component 16 is installed on the lower trimming component 400. The third height adjustment component 16 and the fourth height adjustment component 22 have the same function and working principle as the first height adjustment component 11 and the second height adjustment component 14, all of which are designed to adapt to plates of different thicknesses. Therefore, the third height adjustment component 16 and the fourth height adjustment component 22 will not be described in detail here.

[0037] For example, the sliding assembly 200 further includes a column 12 and a longitudinal guide rail 7. The longitudinal guide rail 7 is mounted on the column 12, and the column 12 is fixedly connected to the lower base 24. The upper scraping component 10, the lower scraping component 13, the upper trimming component 300, and the lower trimming component 400 are all slidably mounted on the longitudinal guide rail 7 so that the upper scraping component 10, the lower scraping component 13, the upper trimming component 300, and the lower trimming component 400 can all slide along the longitudinal guide rail 7.

[0038] The upper trimming part 300 is slidably mounted on the longitudinal guide rail 7 via the upper trimming connector 20, the lower trimming part 400 is slidably mounted on the longitudinal guide rail 7 via the lower trimming connector 15, and the upper trimming knife 19 and the lower trimming knife 17 are slidably mounted on the longitudinal guide rail 7 via the slider seat 6.

[0039] For example, the blocking plate 18 is mounted on the lower trimming member 400, and the blocking block 31 is mounted on the lower scraping member 13.

[0040] Understandably, the distance between the baffle plate 18 and the baffle block 31 in the horizontal direction (left and right in the figure) is adjustable to allow them to move closer to or further away from the plate.

[0041] For example, the fixing component 100 also includes a pressure regulating valve 25, which is connected to the cylinder 30 and is used to adjust the pressure of the cylinder 30, thereby controlling the output distance of the cylinder 30 and thus controlling the moving distance of the drive upper scraping component 10.

[0042] For example, it also includes three vent pins. Two vent pins are connected to the cylinder 30. One of these two vent pins is used to control the cylinder 30 to reduce the pressure, and the other is used to control the cylinder 30 to increase the pressure. The remaining vent pin is connected to the upper scraper 10 through an internal air passage on the fixed component 100 and / or the sliding component 200, so that by inputting gas, gas can be output to the scraper blade (not shown in the figure) on the upper scraper 10 to blow away impurities such as sawdust and residual edge banding tape.

[0043] Both the upper scraping member 10 and the lower scraping member 13 are provided with scraping edges, which are used to scrape the edge sealing tape.

[0044] For example, the fixed component 100 includes a main gear 2, and the sliding component 200 includes a driven gear 28 and a timing belt 27. The output end of the drive input tool holder 1 is connected to the main gear 2. One end of the timing belt 27 is wound around the main gear 2, and the other end of the timing belt 27 is wound around the driven gear 28. The driven gear 28 is connected to the rotating shaft 23, so that the drive input tool holder 1 can drive the rotating shaft 23 to rotate, thereby driving the upper trimming tool 19 and the lower trimming tool 17 to rotate.

[0045] For example, the sliding component 200 further includes a tensioning component 33, which is mounted on the lower base 24. The synchronous belt 27 is wound around the tensioning component 33, and the tensioning component 33 is used to adjust the tension of the synchronous belt 27 to adjust the tension of the synchronous belt 27.

[0046] Understandably, the tensioning assembly 33 includes several tensioning pulleys, and the synchronous belt 27 is wound around each tensioning pulley so that the synchronous belt 27 can be wound in a bent manner around the tensioning pulley, thereby adjusting the tension of the synchronous belt 27 and adjusting the tension of the synchronous belt 27.

Any other functionally equivalent embodiments fall within the scope of protection of the invention. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the scope of protection of the claims of this invention.
